Label under image in UIButton
IosImageTextUibuttonLabelIos Problem Overview
I'm trying to create a button which has some text beneath the icon (sorta like the app buttons) however it seems to be quite difficult to achieve. Any ideas how can I go about get the text to display below the image with a UIButton?

Or you can just use this category:
ObjC
@interface UIButton (VerticalLayout)
- (void)centerVerticallyWithPadding:(float)padding;
- (void)centerVertically;
@end
@implementation UIButton (VerticalLayout)
- (void)centerVerticallyWithPadding:(float)padding {
CGSize imageSize = self.imageView.frame.size;
CGSize titleSize = self.titleLabel.frame.size;
CGFloat totalHeight = (imageSize.height + titleSize.height + padding);
self.imageEdgeInsets = UIEdgeInsetsMake(- (totalHeight - imageSize.height),
0.0f,
0.0f,
- titleSize.width);
self.titleEdgeInsets = UIEdgeInsetsMake(0.0f,
- imageSize.width,
- (totalHeight - titleSize.height),
0.0f);
self.contentEdgeInsets = UIEdgeInsetsMake(0.0f,
0.0f,
titleSize.height,
0.0f);
}
- (void)centerVertically {
const CGFloat kDefaultPadding = 6.0f;
[self centerVerticallyWithPadding:kDefaultPadding];
}
@end
Swift extension
extension UIButton {
func centerVertically(padding: CGFloat = 6.0) {
guard
let imageViewSize = self.imageView?.frame.size,
let titleLabelSize = self.titleLabel?.frame.size else {
return
}
let totalHeight = imageViewSize.height + titleLabelSize.height + padding
self.imageEdgeInsets = UIEdgeInsets(
top: -(totalHeight - imageViewSize.height),
left: 0.0,
bottom: 0.0,
right: -titleLabelSize.width
)
self.titleEdgeInsets = UIEdgeInsets(
top: 0.0,
left: -imageViewSize.width,
bottom: -(totalHeight - titleLabelSize.height),
right: 0.0
)
self.contentEdgeInsets = UIEdgeInsets(
top: 0.0,
left: 0.0,
bottom: titleLabelSize.height,
right: 0.0
)
}
}
Suggestion:
If button height is less than totalHeight, then image will draw outside borders.
imageEdgeInset.top should be:
max(0, -(totalHeight - imageViewSize.height))
Solution 2 - Ios
In Xcode, you can simply set the Edge Title Left Inset to negative the width of the image. This will display the label in the center of the image.
To get the label to display below the image (sorta like the app buttons), you may need to set the Edge Title Top Inset to some positive number.
Edit: Here is some code to achieve that without using Interface Builder:
/// This will move the TitleLabel text of a UIButton to below it's Image and Centered.
/// Note: No point in calling this function before autolayout lays things out.
/// - Parameter padding: Some extra padding to be applied
func centerVertically(padding: CGFloat = 18.0) {
// No point in doing anything if we don't have an imageView size
guard let imageFrame = imageView?.frame else { return }
titleLabel?.numberOfLines = 0
titleEdgeInsets.left = -(imageFrame.width + padding)
titleEdgeInsets.top = (imageFrame.height + padding)
}
Please note this won't work if you're using autolayout and the button didn't get layed out in the screen yet via constraints.

This is a simple centered title button implemented in Swift by overriding titleRect(forContentRect:) and imageRect(forContentRect:). It also implements intrinsicContentSize for use with AutoLayout.
import UIKit
class CenteredButton: UIButton
{
override func titleRect(forContentRect contentRect: CGRect) -> CGRect {
let rect = super.titleRect(forContentRect: contentRect)
return CGRect(x: 0, y: contentRect.height - rect.height + 5,
width: contentRect.width, height: rect.height)
}
override func imageRect(forContentRect contentRect: CGRect) -> CGRect {
let rect = super.imageRect(forContentRect: contentRect)
let titleRect = self.titleRect(forContentRect: contentRect)
return CGRect(x: contentRect.width/2.0 - rect.width/2.0,
y: (contentRect.height - titleRect.height)/2.0 - rect.height/2.0,
width: rect.width, height: rect.height)
}
override var intrinsicContentSize: CGSize {
let size = super.intrinsicContentSize
if let image = imageView?.image {
var labelHeight: CGFloat = 0.0
if let size = titleLabel?.sizeThatFits(CGSize(width: self.contentRect(forBounds: self.bounds).width, height: CGFloat.greatestFiniteMagnitude)) {
labelHeight = size.height
}
return CGSize(width: size.width, height: image.size.height + labelHeight + 5)
}
return size
}
override init(frame: CGRect) {
super.init(frame: frame)
centerTitleLabel()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
centerTitleLabel()
}
private func centerTitleLabel() {
self.titleLabel?.textAlignment = .center
}
}

Look at this great answer in Swift.
extension UIButton {
func alignImageAndTitleVertically(padding: CGFloat = 6.0) {
let imageSize = self.imageView!.frame.size
let titleSize = self.titleLabel!.frame.size
let totalHeight = imageSize.height + titleSize.height + padding
self.imageEdgeInsets = UIEdgeInsets(
top: -(totalHeight - imageSize.height),
left: 0,
bottom: 0,
right: -titleSize.width
)
self.titleEdgeInsets = UIEdgeInsets(
top: 0,
left: -imageSize.width,
bottom: -(totalHeight - titleSize.height),
right: 0
)
}
}

Subclass UIButton. Override -layoutSubviews to move the built-in subviews into new positions:
- (void)layoutSubviews
{
[super layoutSubviews];
CGRect frame = self.imageView.frame;
frame = CGRectMake(truncf((self.bounds.size.width - frame.size.width) / 2), 0.0f, frame.size.width, frame.size.height);
self.imageView.frame = frame;
frame = self.titleLabel.frame;
frame = CGRectMake(truncf((self.bounds.size.width - frame.size.width) / 2), self.bounds.size.height - frame.size.height, frame.size.width, frame.size.height);
self.titleLabel.frame = frame;
}

Refactored icecrystal23`s answer.
Swift 3, works with autolayouts, xib, storyboards, can be animated.
Button in orginal icecrystal23`s answer had a badly calculated frame. I think I fixed that.
Edit: Updated to Swift 5 and made work inside Interface Builder / Storyboards
Edit: Updated to support localization (ltr/rtl) per Alexsander Akers' comment on the answer below
import UIKit
@IBDesignable
class VerticalButton: UIButton {
@IBInspectable public var padding: CGFloat = 20.0 {
didSet {
setNeedsLayout()
}
}
override var intrinsicContentSize: CGSize {
let maxSize = CGSize(width: CGFloat.greatestFiniteMagnitude, height: CGFloat.greatestFiniteMagnitude)
if let titleSize = titleLabel?.sizeThatFits(maxSize), let imageSize = imageView?.sizeThatFits(maxSize) {
let width = ceil(max(imageSize.width, titleSize.width))
let height = ceil(imageSize.height + titleSize.height + padding)
return CGSize(width: width, height: height)
}
return super.intrinsicContentSize
}
override func layoutSubviews() {
if let image = imageView?.image, let title = titleLabel?.attributedText {
let imageSize = image.size
let titleSize = title.size()
if effectiveUserInterfaceLayoutDirection == .leftToRight {
titleEdgeInsets = UIEdgeInsets(top: 0.0, left: -imageSize.width, bottom: -(imageSize.height + padding), right: 0.0)
imageEdgeInsets = UIEdgeInsets(top: -(titleSize.height + padding), left: 0.0, bottom: 0.0, right: -titleSize.width)

corrected one of the answers here:
Swift 3:

override func titleRect(forContentRect contentRect: CGRect) -> CGRect {
let rect = super.titleRect(forContentRect: contentRect)
let imageRect = super.imageRect(forContentRect: contentRect)

If you subclass UIButton and override layoutSubviews, you can use the below to center the image and place the title centered below it:
kTextTopPadding is a constant you'll have to introduce that determines the space between the image and the text below it.
-(void)layoutSubviews {
[super layoutSubviews];
// Move the image to the top and center it horizontally
CGRect imageFrame = self.imageView.frame;
imageFrame.origin.y = 0;
imageFrame.origin.x = (self.frame.size.width / 2) - (imageFrame.size.width / 2);
self.imageView.frame = imageFrame;
// Adjust the label size to fit the text, and move it below the image
CGRect titleLabelFrame = self.titleLabel.frame;
CGSize labelSize = [self.titleLabel.text sizeWithFont:self.titleLabel.font
constrainedToSize:CGSizeMake(self.frame.size.width, CGFLOAT_MAX)
lineBreakMode:NSLineBreakByWordWrapping];
titleLabelFrame.size.width = labelSize.width;
titleLabelFrame.size.height = labelSize.height;
titleLabelFrame.origin.x = (self.frame.size.width / 2) - (labelSize.width / 2);
titleLabelFrame.origin.y = self.imageView.frame.origin.y + self.imageView.frame.size.height + kTextTopPadding;
self.titleLabel.frame = titleLabelFrame;
}

Dave's solution in Swift:
override func layoutSubviews() {
super.layoutSubviews()
if let imageView = self.imageView {
imageView.frame.origin.x = (self.bounds.size.width - imageView.frame.size.width) / 2.0
imageView.frame.origin.y = 0.0
}
if let titleLabel = self.titleLabel {
titleLabel.frame.origin.x = (self.bounds.size.width - titleLabel.frame.size.width) / 2.0
titleLabel.frame.origin.y = self.bounds.size.height - titleLabel.frame.size.height
}
}

This is a modified version of Erik W's excellent answer. But instead of placing the image centered at the TOP of the view, it places the image and the label centred in the view as a group.
The difference is:

CGRect titleLabelFrame = self.titleLabel.frame;
CGSize labelSize = [self.titleLabel.text sizeWithFont:self.titleLabel.font constrainedToSize:CGSizeMake(self.frame.size.width, CGFLOAT_MAX) lineBreakMode:NSLineBreakByWordWrapping];
CGRect imageFrame = self.imageView.frame;
CGSize fitBoxSize = (CGSize){.height = labelSize.height + kTextTopPadding + imageFrame.size.height, .width = MAX(imageFrame.size.width, labelSize.width)};
CGRect fitBoxRect = CGRectInset(self.bounds, (self.bounds.size.width - fitBoxSize.width)/2, (self.bounds.size.height - fitBoxSize.height)/2);

imageFrame.origin.x = CGRectGetMidX(fitBoxRect) - (imageFrame.size.width/2);
self.imageView.frame = imageFrame;
// Adjust the label size to fit the text, and move it below the image
titleLabelFrame.size.width = labelSize.width;
titleLabelFrame.size.height = labelSize.height;
titleLabelFrame.origin.x = (self.frame.size.width / 2) - (labelSize.width / 2);
titleLabelFrame.origin.y = fitBoxRect.origin.y + imageFrame.size.height + kTextTopPadding;
self.titleLabel.frame = titleLabelFrame;
}
FYI: This can break when combined with UIView animations, as layoutSubviews is called during them.

On iOS 11/ Swift 4 none of the above answers really worked for me. I found some examples and put my spin on it:
extension UIButton {
func centerImageAndButton(_ gap: CGFloat, imageOnTop: Bool) {
guard let imageView = self.currentImage,
let titleLabel = self.titleLabel?.text else { return }
let sign: CGFloat = imageOnTop ? 1 : -1
self.titleEdgeInsets = UIEdgeInsetsMake((imageView.size.height + gap) * sign, -imageView.size.width, 0, 0);
let titleSize = titleLabel.size(withAttributes:[NSAttributedStringKey.font: self.titleLabel!.font!])
self.imageEdgeInsets = UIEdgeInsetsMake(-(titleSize.height + gap) * sign, 0, 0, -titleSize.width)
}
}
Hope this helps someone.

Updated Kenny Winker's answer since sizeWithFont was deprecated in iOS 7.
-(void)layoutSubviews {
[super layoutSubviews];
int kTextTopPadding = 3;
CGRect titleLabelFrame = self.titleLabel.frame;
CGRect labelSize = [self.titleLabel.text boundingRectWithSize:CGSizeMake(CGFLOAT_MAX, CGRectGetHeight(self.bounds)) options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSFontAttributeName:self.titleLabel.font} context:nil];
CGRect imageFrame = self.imageView.frame;
CGSize fitBoxSize = (CGSize){.height = labelSize.size.height + kTextTopPadding + imageFrame.size.height, .width = MAX(imageFrame.size.width, labelSize.size.width)};
CGRect fitBoxRect = CGRectInset(self.bounds, (self.bounds.size.width - fitBoxSize.width)/2, (self.bounds.size.height - fitBoxSize.height)/2);

imageFrame.origin.x = CGRectGetMidX(fitBoxRect) - (imageFrame.size.width/2);
self.imageView.frame = imageFrame;
// Adjust the label size to fit the text, and move it below the image
titleLabelFrame.size.width = labelSize.size.width;

Swift 5, AutoLayout
I implemented combination of some approaches and this works best for me. Trick is in overriding titleRect(forContentRect:), imageRect(forContentRect:) methods and intrinsicContentSize getter with calculated values of those views.
Result:
final class CustomButton: UIButton {
override func titleRect(forContentRect contentRect: CGRect) -> CGRect {
let superRect = super.titleRect(forContentRect: contentRect)
return CGRect(
x: 0,
y: contentRect.height - superRect.height,
width: contentRect.width,
height: superRect.height
)
}
override func imageRect(forContentRect contentRect: CGRect) -> CGRect {
let superRect = super.imageRect(forContentRect: contentRect)
return CGRect(
x: contentRect.width / 2 - superRect.width / 2,
y: (contentRect.height - titleRect(forContentRect: contentRect).height) / 2 - superRect.height / 2,
width: superRect.width,
height: superRect.height
)
}
override var intrinsicContentSize: CGSize {
_ = super.intrinsicContentSize
guard let image = imageView?.image else { return super.intrinsicContentSize }
let size = titleLabel?.sizeThatFits(contentRect(forBounds: bounds).size) ?? .zero
let spacing: CGFloat = 12
return CGSize(width: max(size.width, image.size.width), height: image.size.height + size.height + spacing)
}
override init(frame: CGRect) {
super.init(frame: frame)
setup()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
setup()
}
private func setup() {
titleLabel?.textAlignment = .center
}
}
The solution above may not work in iOS 12 and older. In this case create constants with fixed image size and label height depending on font size.
final class CustomButton: UIButton {
private enum Constants {
static let imageSize: CGFloat = 48
static let titleHeight = yourFont.pointSize - yourFont.descender
}
override func titleRect(forContentRect contentRect: CGRect) -> CGRect {
_ = super.titleRect(forContentRect: contentRect)
return CGRect(
x: 0,
y: contentRect.height - Constants.titleHeight,
width: contentRect.width,
height: Constants.titleHeight
)
}
override func imageRect(forContentRect contentRect: CGRect) -> CGRect {
return CGRect(
x: contentRect.width / 2 - Constants.imageSize / 2,
y: (contentRect.height - titleRect(forContentRect: contentRect).height) / 2 - Constants.imageSize / 2,
width: Constants.imageSize,
height: Constants.imageSize
)
}
override var intrinsicContentSize: CGSize {
_ = super.intrinsicContentSize
let size = titleLabel?.sizeThatFits(contentRect(forBounds: bounds).size) ?? .zero
let spacing: CGFloat = 12
return CGSize(
width: max(size.width, Constants.imageSize),
height: Constants.imageSize + Constants.titleHeight + spacing
)
}
override init(frame: CGRect) {
super.init(frame: frame)

private func setup() {
titleLabel?.textAlignment = .center

Localization Friendly Solution:
So many great solutions guys, but I'd like to add a note here for those who use localization.
You need to reverse the left and right EdgeInstets values to get the button laid out correctly in case of a change of language direction from LtR to RtL.
Using a similar solution I'd implement it as follows:
extension UIButton {
func alignVertical(spacing: CGFloat, lang: String) {
guard let imageSize = self.imageView?.image?.size,
let text = self.titleLabel?.text,
let font = self.titleLabel?.font
else { return }
let labelString = NSString(string: text)
let titleSize = labelString.size(
withAttributes: [NSAttributedString.Key.font: font]
)
var titleLeftInset: CGFloat = -imageSize.width
var titleRigtInset: CGFloat = 0.0
var imageLeftInset: CGFloat = 0.0
var imageRightInset: CGFloat = -titleSize.width
if Locale.current.languageCode! != "en" { // If not Left to Right language
titleLeftInset = 0.0
titleRigtInset = -imageSize.width
imageLeftInset = -titleSize.width
imageRightInset = 0.0
}
self.titleEdgeInsets = UIEdgeInsets(
top: 0.0,
left: titleLeftInset,
bottom: -(imageSize.height + spacing),
right: titleRigtInset
)
self.imageEdgeInsets = UIEdgeInsets(
top: -(titleSize.height + spacing),
left: imageLeftInset,
bottom: 0.0,
right: imageRightInset
)
let edgeOffset = abs(titleSize.height - imageSize.height) / 2.0;
self.contentEdgeInsets = UIEdgeInsets(
top: edgeOffset,
left: 0.0,
bottom: edgeOffset,
right: 0.0
)
}
}
Solution 18 - Ios
You just have to adjust all three edge insets based on the size of your image and title label:
button.contentEdgeInsets = UIEdgeInsetsMake(0, 0, titleLabelBounds.height + 4, 0)
button.titleEdgeInsets = UIEdgeInsetsMake(image.size.height + 8, -image.size.width, 0, 0)
button.imageEdgeInsets = UIEdgeInsetsMake(0, 0, 0, -titleLabelBounds.width)
You can get the title label bounds by calling sizeToFit after setting its text. The horizontal spacing should work regardless of the size of the text, font and image but I don't know of a single solution to get the vertical spacing and bottom content edge inset consistent.

Here is "Bear With Me"s answer as a subclass in Swift 2.0. To use it just change your button class in Interface Builder to VerticalButton and it will magically update the preview.
I also updated it to calculate the correct intrinsic content size for autolayout.
import UIKit
@IBDesignable
class VerticalButton: UIButton {
@IBInspectable var padding: CGFloat = 8
override func prepareForInterfaceBuilder() {
super.prepareForInterfaceBuilder()
update()
}
override func layoutSubviews() {
super.layoutSubviews()
update()
}
func update() {
let imageBounds = self.imageView!.bounds
let titleBounds = self.titleLabel!.bounds
let totalHeight = CGRectGetHeight(imageBounds) + padding + CGRectGetHeight(titleBounds)
self.imageEdgeInsets = UIEdgeInsets(
top: -(totalHeight - CGRectGetHeight(imageBounds)),
left: 0,
bottom: 0,
right: -CGRectGetWidth(titleBounds)
)
self.titleEdgeInsets = UIEdgeInsets(
top: 0,
left: -CGRectGetWidth(imageBounds),
bottom: -(totalHeight - CGRectGetHeight(titleBounds)),
right: 0
)
}
override func intrinsicContentSize() -> CGSize {
let imageBounds = self.imageView!.bounds
let titleBounds = self.titleLabel!.bounds
let width = CGRectGetWidth(imageBounds) > CGRectGetWidth(titleBounds) ? CGRectGetWidth(imageBounds) : CGRectGetWidth(titleBounds)
let height = CGRectGetHeight(imageBounds) + padding + CGRectGetHeight(titleBounds)
return CGSizeMake(width, height)
}
}

I took a combination of the answers here and came up with one that seems to be working for me, in Swift. I don't love how I just overrode the insets, but it works. I'd be open to suggested improvements in the comments. It seems to work correctly with sizeToFit() and with auto layout.
import UIKit
/// A button that displays an image centered above the title. This implementation
/// only works when both an image and title are set, and ignores
/// any changes you make to edge insets.
class CenteredButton: UIButton
{
let padding: CGFloat = 0.0
override func layoutSubviews() {
if imageView?.image != nil && titleLabel?.text != nil {
let imageSize: CGSize = imageView!.image!.size
titleEdgeInsets = UIEdgeInsetsMake(0.0, -imageSize.width, -(imageSize.height + padding), 0.0)
let labelString = NSString(string: titleLabel!.text!)
let titleSize = labelString.sizeWithAttributes([NSFontAttributeName: titleLabel!.font])
imageEdgeInsets = UIEdgeInsetsMake(-(titleSize.height + padding), 0.0, 0.0, -titleSize.width)
let edgeOffset = abs(titleSize.height - imageSize.height) / 2.0;
contentEdgeInsets = UIEdgeInsetsMake(edgeOffset, 0.0, edgeOffset, 0.0)
}
super.layoutSubviews()
}
override func sizeThatFits(size: CGSize) -> CGSize {
let defaultSize = super.sizeThatFits(size)
if let titleSize = titleLabel?.sizeThatFits(size),
let imageSize = imageView?.sizeThatFits(size) {
return CGSize(width: ceil(max(imageSize.width, titleSize.width)), height: ceil(imageSize.height + titleSize.height + padding))
}
return defaultSize
}
override func intrinsicContentSize() -> CGSize {
let size = sizeThatFits(CGSize(width: CGFloat.max, height: CGFloat.max))
return size
}
}

Use this two methods:
func titleRect(forContentRect contentRect: CGRect) -> CGRect
func imageRect(forContentRect contentRect: CGRect) -> CGRect
Example:
class VerticalButton: UIButton {
override func titleRect(forContentRect contentRect: CGRect) -> CGRect {
let titleRect = super.titleRect(forContentRect: contentRect)
let imageRect = super.imageRect(forContentRect: contentRect)
return CGRect(x: 0,
y: contentRect.height - (contentRect.height - padding - imageRect.size.height - titleRect.size.height) / 2 - titleRect.size.height,
width: contentRect.width,
height: titleRect.height)

That's definitely is an overkill for this question, however... In one of my projects I first had to implement a button with icon aligned leftmost. Then we got another button with title under image. I searched for an existing solution but with no luck So, here goes the alignable button:
@IBDesignable

override class var requiresConstraintBasedLayout: Bool {
return true
}
@objc enum IconAlignment: Int {
case top, left, right, bottom
}

set {
iconAlignment = IconAlignment(rawValue: newValue) ?? .left
}
get {

}
}
var iconAlignment: IconAlignment = .left
@IBInspectable var titleAlignmentValue: Int {
set {
titleAlignment = NSTextAlignment(rawValue: newValue) ?? .left
}
get {
return titleAlignment.rawValue
}
}
var titleAlignment: NSTextAlignment = .left
// MARK: - Corner Radius
@IBInspectable
var cornerRadius: CGFloat {
get {
return layer.cornerRadius
}
set {
layer.masksToBounds = (newValue != 0)
layer.cornerRadius = newValue
}
}

override var intrinsicContentSize: CGSize {
switch iconAlignment {

I think one of the best ways to do that is by subclassing UIButton and override some rendering methods:
- (void)awakeFromNib
{
[super awakeFromNib];
[self setupSubViews];
}
- (instancetype)init
{
if (self = [super init])
{
[self setupSubViews];
}
return self;
}
- (void)setupSubViews
{
[self.imageView setTranslatesAutoresizingMaskIntoConstraints:NO];
[self addConstraint:[NSLayoutConstraint constraintWithItem:self attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:self.imageView attribute:NSLayoutAttributeCenterX multiplier:1 constant:0]];
[self.titleLabel setTranslatesAutoresizingMaskIntoConstraints:NO];
[self addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|[imageView][titleLabel]|" options:NSLayoutFormatAlignAllCenterX metrics:nil views:@{@"imageView": self.imageView, @"titleLabel": self.titleLabel}]];
}
- (CGSize)intrinsicContentSize
{
CGSize imageSize = self.imageView.image.size;
CGSize titleSize = [self.titleLabel.text sizeWithAttributes:@{NSFontAttributeName: self.titleLabel.font}];
return CGSizeMake(MAX(imageSize.width, titleSize.width), imageSize.height + titleSize.height);

I found that Simeon's answer was probably the best but it was giving me strange results on some buttons and I just couldn't work out why. So using his answer as a base I implemented my buttons as per below:
#define PADDING 2.0f
@implementation OOButtonVerticalImageText
-(CGSize) intrinsicContentSize {
CGSize size = [super intrinsicContentSize];
CGFloat labelHeight = 0.0f;
CGSize titleSize = [self.titleLabel sizeThatFits:CGSizeMake([self contentRectForBounds:self.bounds].size.width, CGFLOAT_MAX)];
labelHeight = titleSize.height;
return CGSizeMake(MAX(titleSize.width, self.imageView.image.size.width), self.imageView.image.size.height + labelHeight + PADDING);
}
-(void) layoutSubviews {
[super layoutSubviews];
CGSize titleSize = [self.titleLabel sizeThatFits:CGSizeMake([self contentRectForBounds:self.bounds].size.width, CGFLOAT_MAX)];
self.titleLabel.frame = CGRectMake((self.bounds.size.width - titleSize.width)/2.0f,
self.bounds.size.height - titleSize.height - PADDING,
titleSize.width,
titleSize.height);
CGSize ivSize = self.imageView.frame.size;
self.imageView.frame = CGRectMake((self.bounds.size.width - ivSize.width)/2.0f,
self.titleLabel.frame.origin.y - ivSize.height - PADDING,
ivSize.width,

Using @Robert Dresler solution wasn't working for me on IOS 15, so I extended the button class by adding a condition to check if is IOS 15 and use the new ui button configuration for IOS 15
final class ImageButton: UIButton {
private enum Constants {
static let imageSize: CGFloat = 40
static let titleHeight: CGFloat = 12
}
override func titleRect(forContentRect contentRect: CGRect) -> CGRect {
if #available(iOS 15, *) {
return super.titleRect(forContentRect: contentRect)
}
else {
_ = super.titleRect(forContentRect: contentRect)
return CGRect(
x: 0,
y: contentRect.height - Constants.titleHeight,
width: contentRect.width,
height: Constants.titleHeight
)
}
}
override func imageRect(forContentRect contentRect: CGRect) -> CGRect {
if #available(iOS 15, *) {
return super.imageRect(forContentRect: contentRect)
} else {
return CGRect(
x: contentRect.width / 2 - Constants.imageSize / 2,
y: (contentRect.height - titleRect(forContentRect: contentRect).height) / 2 - Constants.imageSize / 2,
width: Constants.imageSize,
height: Constants.imageSize
)
}
}
override var intrinsicContentSize: CGSize {
if #available(iOS 15, *) {
return super.intrinsicContentSize
}
else {
_ = super.intrinsicContentSize
let size = titleLabel?.sizeThatFits(contentRect(forBounds: bounds).size) ?? .zero
let spacing: CGFloat = 12
return CGSize(
width: max(size.width, Constants.imageSize),
height: Constants.imageSize + Constants.titleHeight + spacing
)
}
}
override init(frame: CGRect) {
super.init(frame: frame)
setup()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
setup()
}
private func setup() {
if #available(iOS 15, *) {
var myConfiguration = UIButton.Configuration.plain()
myConfiguration.imagePlacement = .top
self.configuration = myConfiguration
} else {
titleLabel?.textAlignment = .center
}
}
}
This solution works on IOS 12 to 15

That's it. Works like charm. Problem may appear if button will be to small to fit title and text.

If you are using custom fonts the calculation for the titleLabel size won't work properly, you should replace it with
let titleLabelSize = self.titleLabel?.text?.size(withAttributes: [NSAttributedStringKey.font: self.titleLabel!.font!])
Solution 29 - Ios
Instead of going through hell trying to position the icon and the text with edge insets, you could create a NSAttributedString with your image as an attachment and set it to your button's attributed title instead:
let titleText = NSAttributedString(string: yourTitle, attributes: attributes)
let imageAttachment = NSTextAttachment()
imageAttachment.image = yourImage
let title = NSMutableAttributedString(string: "")
title.append(NSAttributedString(attachment: imageAttachment))
title.append(titleText)
button.setAttributedTitle(title, for: .normal)

Another way I found:
UIButton has 2 UIImageViews. First of them we can reach using UIButton's imageView property. Another UIImage view is inaccessible via UIButton's properties, but that another UIImageView perfectly fits to implement centered button. To access that background image view I added an extension:
extension UIButton {
var backgroundImageView: UIImageView? {
return subviews.first(where: { $0.isKind(of: UIImageView.self) && $0 != imageView }) as? UIImageView
}
}
The next step is to setup the button:
centeredButton.setBackgroundImage(perfectImage, for: .normal) // This sets image to Button's backgroundImageView
centeredButton.backgroundImageView?.contentMode = .top // This moves image to the top of the Button's frame
centeredButton.contentVerticalAlignment = .bottom // This moves label to the bottom of the Button's frame.
The next step is to set padding between image and label. You can make this by adding height constraint to the button. The image will alway be on the top, label on the bottom.
Solution 34 - Ios
Its pretty simple.
Instead of this:
button.setImage(UIImage(named: "image"), forState: .Normal)
Use this:
button.setBackgroundImage(UIImage(named: "image", forState: .Normal)
Then you can add text on the button easily using:
// button.titleLabel!.font = UIFont(name: "FontName", size: 30)
button.setTitle("TitleText", forState: UIControlState.Normal)
